To all whom it may concern.-

Be it known that I, MIoHAEL BOWES, a citizen of the United States,residing at Raleigh, in the county ot'IVake and State of North Carolina,have invented certain new and useful Improvements in Dumping-Carts, ofwhich the following is a full, clear, and exact description.

This invention relates to carts or wagons in which the body is tipped ortilted to unload the contents, the tail-board being'temporarily removed.It has for its object to provide im proved means for tilting the bodyand for removing and replacing the tail-board automatically. The body ofthe vehicle when in its normal or horizontal position is engaged by alatch or catch,which holds said body stationary and prevents itsaccidental tilting, and this latch or catch is so connected with adevice for tilting the said body that one movement of a handle connectedwith said parts first releases the latch or catch and then tilts thecart-body. The tilting device employed consists of an arm or arock-shaft, which arm projects under the front end of the body, so thatwhen the rock-shaft is turned in the proper direction the tilting-armlifts the front of the body and dumps the load. The retaining-catch isattached to or carried by the rockshaft, and is withdrawn when thelatter is turned, as stated. A spring is arranged to return therock-shaft, the tilting-arm, and the catch as soon as the handle isreleased; and the catch is so constructed that when the cartbody isreturned to its normal position the catch snaps into engagement andretains it in place.

It is not new to use a rock-shaft provided with a tiltingarm to raisethe front of the cart-body for dumping. It is. however, be lieved to benew so to combine the retainingcatch with the rock-shaft and arm thatone movement of the handle or operating device releases the catch anddumps the load, and also to employ the particular devices .andarrangement described. Heretofore the cartbody was connected by a chainwith a second arm of the rock-shaft, and a latch or catch engaging athird arm prevented the rock-shaft from being moved until it wasreleased.

In order that the tail-board may be removed when the body is tilted, it(the tail-board) is connected with asu jiporting-frame, which preventsit from descending with the tail end of the cart-body. It is hinged tothis frame or support, so that thelower part can swing out to 1 passaround the corners of the sides, or to allow the load to fall out. Whenin place at the end of the cart, it is prevented from swinging bystop-pieces on the cartbody. When after dumping the cart-body'isreplaced,the bottom of the tail-board is swung out bycontact with thesides of the cart, so as to pass around the square corners.

Herctofore the tail board has been fastened to a frame or support, whichupholds it when the cart or wagon body is tilted; but in all cases,sofar as lamaware, it has been fastened to the frame so that it cannotturn, the sides of the cart-body being cut slanting at the ends in orderto allow the tailof the cart to descend without obstruction from thetail-board,

In order to apply the frame or support to uphold the tail-board to theordinary form of cart, which has the shafts hinged to the axle and thelatter fastened to' the cart-body, said support or frame is fastened tothe shafts in front of the axle, and extends past the axle to the tailof the cart, where it is connected with the tail-board.

The accompanying drawings represent a dumping cart embodying theinvention in what is considered the best mode of applying the principlethereof.

Figure l is a view in vertical longitudinal section, showing thecart-body and tail-board in their normal position; Fig. 2is a side view,

showing the position of the parts in tilting; Fig. 3 is a plan, and Fig.4 is a rear end View.

A is the eart-body,which is supported at the middle. and there fastenedto the axle B. The shafts O are hinged to the front of the axle, as isvery common. The rock-shaft D, journaled in bearings on the shafts O,has an arm, E, that extends under the front end of the cart-body. It isfurther provided with a bent or notched arm, F,which serves as a catchand engages the ledge G on the front of the cart-body; and also with ahandle, H, and retractile spring I, in the form of a spiraltension-spring. The tail-board K is fastened at the top to thecross-shaft L, which is journaled at the ends in the frames M on eachside of the cart-body. As shown, the tail-board is suspended from apoint in front of the same, in order that the bottom may tend to swingforward, and thus give to the tail-board the proper angle at which tomeet and enter into position behind the rising cart-body. The frames Mare attached to the shafts, and consist each of the bars 1 2 3 4, ofstrap-iron or other suitable material. The bars 1 and 2 are screwed,bolted, or otherwise fastened to the crosspiece N of the shafts. The bar3 is fastened to the side of the corresponding shaft. The frames M areconnected together under the axle by the cross-bar 5. The inner end ofthe retractile' spring I is fastened to one of the frames M, the outerend being secured to the handle H. The tail-board fits in between thesides of the cart-body. It is provided at the top on each side with theflat hooks 6, which fit over the end of the side-boards, and at thebottom with the projections or pins 7, which in the normal position ofthe cart-body are confined by stop-pieces, P. These stop-pieces arefastened to the cart-body. As shown,

they extend up a short distance; butthey could be as high as desired.

In order to dump the load,the driver catches hold of the handle H anddraws it forward. He thus turns the rock-shaft D, first withdrawing thecatch F from its position above the ledge G, and then having brought thearm E into contact with the bottom of the cartbody, raising the frontend and tilting the body into the position shown in Fig. 2. Thetail-board, being upheld by the frames M, is removed from the end of thecart and occupies the position shown in full lines in Fig. 2. The bottomof the tail-board has been pushed out of the perpendicular by the actionof the ends of the side pieces against the projections or pins 7. When.the cart-body has been tilted to the position shown,the load willordinarily overbalance and carry the body into the position representedin dotted lines. The position of the tail-board at full-dump is alsoshown in dotted lines.

To return the parts into position for receiving a new load, it is onlynecessary to restore the cart-body to a horizontal position. The top ofthe side pieces will by contact with the projections or pins 7 swing outthe tail-board until said projections or pins pass around the It isevident that modifications may be made as described, so that onemovement of said handle or operating device releases the catch and tiltsthe said vehicle-body, as set forth.

body and the tail-board, of the frames for upholding said tail-board,the latter being hinged to said frames so that it c'a'n'swing on ahorizontal axis in removing and replacing the said tail-board, beingprovided at the bottom with projections or pins which guide thetail-board 8o 3.

4. The combination, with the tilting body, the frames for upholding thetail-board when the vehicle-body is tilted, the tail-board hinged tosaid frames so that it can swing on a horizontal axis, and thestop-pieces on the vehiole-body to prevent the tail-board from swing-'ing out when the said body is horizontal, substantially as described.

5. A dumping-cart comprising the body, the axle fastened on the bottomof said body, the shafts hinged to the axle, the frames fastened to theshafts in front of the axle, and the tail-board connected with saidframes, substantially as described. I

6. The combination, in a dumping-cart,with the body and shafts of thecart, ofthe rockshaft, tilting-arm, catch carried by and movable withthe rock-shaft, retractile spring, frames, and tail-board, saidrock-shaft and frames both being fastened to the shafts, and said framesupholding the tail-board whenever the vehicle-body is tilted by turningthe rockshaft, substantially as described.

In testimony whereof Ihave aflixed my signature in presence of twowitnesses.
